OK, but this is making me question how the Deathknights of Crail are being mind-controlled.

Is it some kinda device transmitting, like, a sound, or a code, in some kinda frequency in their ears/brain?

If so, can this theoretically be reversed, or the frequency changed, so now you have Deathknights who have turned on their Grand Master?
